Objective: The major objective of this study was to prepare and evaluate OnceDaily Sustained Release Matrix Pellets Formulation of Aceclofenac by using Extrusion-Spheronization technique. Methods: The sustained release matrix pellets of Aceclofenac were prepared by industrially applied extrusion spheronization technique. The different formulations were prepared using HPMC K100M LVCR as hydrophi...

Compared to single-unit dosage forms, oral multiparticulate drug-delivery systems (e.g. pellets, granules) offer biopharmaceutical advantages in terms of a more even and predictable distribution and transportation in the gastrointestinal tract. There are different pelletization and granulation techniques available to prepare drug loaded spherical particles or granules. Extrusion Spheronization ...

sion/spheronization affects the properties of the resulting pellets. Pharmaceutical scientists originally directed their focus to extrusion, spheronization and drying which can be seen from the literature. Only a few authors reported investigations concerning the impact of the granulation step. Baert et al. investigated ternary mixtures of microcrystalline cellulose (MCC), a drug substitute and...

The main objective of this study was to prepare colon-specific pellets of budesonide, using pectin as film coating. Pellet cores of budesonide were prepared by extrusion / spheronization technique. Pectin, in different ratios was combined with Eudragit RS30D, Eudragit NE30D or Surelease to produce film coating. The dissolution profiles of pectin coated pellets were investigated in pH of 1.2 (2 ...

BACKGROUND AND THE PURPOSE OF THE STUDY Budesonide is the drug of choice for treatment of active inflammatory bowel disease (IBD). The aim of this study was to develop budesonide pellets based on a novel colon drug delivery system (CODES). METHODS Pellet cores containing lactulose or mannitol were prepared by extrusion/spheronization and coated with an acid soluble polymer (Eudragit E100), hy...

BACKGROUND AND METHODS The aim of this study was to develop an immediate-release pellet formulation with improved drug dissolution and adsorption. Carbamazepine, a poorly water-soluble drug, was adsorbed into mesoporous silica (SBA-15-CBZ) via a wetness impregnation method and then processed by extrusion/spheronization into pellets. Physicochemical characterization of the preparation was carrie...

The oral bioavailability of curcumin is limited, attributed to its low solubility or dissolution and poor absorption. Herein, the study describes formulation curcumin-loaded mixed micelles Gelucire® 48/16 TPGS for rate enhancement. Curcumin was dispersed in these molten lipidic surfactants which then adsorbed on carrier formulated as pellets by extrusion spheronization. Critical micelle concent...
